    摘要: A communication system includes a transmitter that applies an electric field, obtained by modulating an information signal for wideband communication, to a transmission medium. The transmitter includes a transmission electrode, a transmission circuit that outputs the information signal for the wideband communication, and a first band controller that controls a band of the information signal for the wideband communication. When the transmission medium is in contact with the transmission electrode and the transmission medium and the transmission electrode are capacitively coupled to each other, the first band controller performs control to provide a band that is necessary for a receiver to perform demodulation for the wideband communication, and when the transmission medium is not in contact with the transmission electrode, the first band controller performs control to provide a narrower band than the band that is necessary for the wideband communication.

    摘要: A casing contains a circuit substrate. A signal electrode for transmitting and/or receiving an electronic field signal is arranged on a first surface side of the casing. The signal electrode is electrically connected to a conductor, which is an apparatus component, of the circuit substrate. A battery and a reference electrode having an electric field reference potential, which are apparatus components, are arranged on the second surface side of the casing. The sum (Cst) of a capacitance between the signal electrode and the transmission medium and a capacitance between the apparatus component and the transmission medium generated while the first surface is facing the transmission medium is approximately equal to the sum (Cgt) of capacitances between the apparatus components and the transmission medium generated while the second surface is facing the transmission medium.
